Public knew plant was 'threat to water'

The company that spilled toxic chemicals into the drinking water supply in Yancheng, Jiangsu province, should have been closed down a long time ago, the city's mayor said on Sunday.

Local governments must do more to ensure the incident is not repeated and officials must pay more attention to the concerns of the public, Mayor Li Qiang said.

Local people had submitted dozens of complaints about the chemical plant but nothing had been done about it, he said.
